Description
本発明は、フレキシブルコンテナに関する。
The present invention relates to a flexible container.
粉粒体や穀物、野菜等の各種内容物を貯蔵し輸送するために、しばしばフレキシブルコンテナが用いられる。フレキシブルコンテナには様々なタイプのものが存在するが、その1つに、上部に内容物の充填口が形成され、下部にその排出口が形成されるタイプのものがある(特許文献1~3参照)。この種のフレキシブルコンテナは開封時に吊り下げられ、下部の排出口から内容物が取り出される。
Flexible containers are often used to store and transport various contents such as powders, grains, and vegetables. There are various types of flexible containers, and one of them is a type in which a filling port for contents is formed in the upper part and a discharge port is formed in the lower part (Patent Documents 1 to 3). reference). This type of flexible container is hung when opened and the contents are removed from the lower outlet.
特許文献1~3のフレキシブルコンテナは二重構造であり、内容物が充填される内袋と、内袋が収容される外袋とを備える。外袋の底面部には下部開口が形成されており、この下部開口は、開封時以外、底面部において下部開口を規定する縁に連続する花冠状の蓋に覆われている。なお、花冠状の蓋は、特許文献1では「下側外蓋」(16)と呼ばれ、特許文献2では「蓋押さえ片」(16a~16d)と呼ばれ、特許文献3では「菊割部」(18)と呼ばれている。花冠状の蓋は、複数の花弁に対応する部位からなり、これらの部位の中央に通された紐を縛ることにより、これらの部位が底面部と同じ平面内において花冠を形成するかのように放射状に配置され、これにより下部開口が閉じられる。一方、開封時には、この紐の縛りを解くことで、花弁に対応する部位が下方に垂れ下がり、下部開口が開く。そして、この下部開口から引っ張り出される内袋の下部に対応する排出口部を介して、内容物が取り出される。
The flexible container of Patent Documents 1 to 3 has a double structure, and includes an inner bag filled with the contents and an outer bag containing the inner bag. A lower opening is formed on the bottom surface of the outer bag, and the lower opening is covered with a flower crown-shaped lid continuous with the edge defining the lower opening on the bottom surface except when the bag is opened. The flower crown-shaped lid is referred to as "lower outer lid" (16) in Patent Document 1, "lid holding piece" (16a to 16d) in Patent Document 2, and "Kikuwari" in Patent Document 3. It is called the "part" (18). The corolla-shaped lid consists of parts corresponding to multiple petals, and by tying a string passed through the center of these parts, it is as if these parts form a corolla in the same plane as the bottom part. Arranged radially, this closes the lower opening. On the other hand, at the time of opening, by untying this string, the part corresponding to the petals hangs down and the lower opening opens. Then, the contents are taken out through the discharge port portion corresponding to the lower part of the inner bag pulled out from the lower opening.
以上のようなフレキシブルコンテナでは、例えば、開袋時に花冠状の蓋を固定している紐を解いて蓋を開け、内袋の排出口部を引っ張り出し、排出口部の先端のヒートシールされている部分を切断し、排出口部を縛っている紐を解くという作業が必要となる。しかしながら、このような開袋作業は、作業者にとって必ずしも容易でなく、時間の面でも負担となりがちであった。このため、扱いが容易で、作業性の良いフレキシブルコンテナが望まれていた。
In the flexible container as described above, for example, when the bag is opened, the string fixing the flower crown-shaped lid is released, the lid is opened, the discharge port of the inner bag is pulled out, and the tip of the discharge port is heat-sealed. It is necessary to cut the part where it is and untie the string that binds the outlet. However, such an opening operation is not always easy for the operator, and tends to be a burden in terms of time. Therefore, a flexible container that is easy to handle and has good workability has been desired.

以下、図面を参照しつつ、本発明の一実施形態に係るフレキシブルコンテナについて説明する。図1に、本実施形態に係るフレキシブルコンテナ(以下、単にコンテナということがある)1の側面図を示す。以下では、説明の便宜のため、図1の上下方向を「上下」と称し、これを基準に説明を行う。
Hereinafter, the flexible container according to the embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a side view of a flexible container (hereinafter, may be simply referred to as a container) 1 according to the present embodiment. In the following, for convenience of explanation, the vertical direction of FIG. 1 is referred to as "up and down", and the explanation will be given based on this.
<1.フレキシブルコンテナの全体構成>
フレキシブルコンテナ1は、内容物を収容するためのコンテナであり、内容物を貯蔵し輸送するために用いられる。フレキシブルコンテナ1は、その名のとおり柔軟な素材から構成されている。そのため、コンテナ1は、内容物が充填されている状態では立体的に広がるが、空の状態では扁平状に折り畳むことができる。 <1. Overall configuration of flexible container>
Theflexible container 1 is a container for accommodating the contents, and is used for storing and transporting the contents. As the name implies, the flexible container 1 is made of a flexible material. Therefore, the container 1 expands three-dimensionally when the contents are filled, but can be folded flat when the container 1 is empty.
フレキシブルコンテナ1は、内容物を収容するためのコンテナであり、内容物を貯蔵し輸送するために用いられる。フレキシブルコンテナ1は、その名のとおり柔軟な素材から構成されている。そのため、コンテナ1は、内容物が充填されている状態では立体的に広がるが、空の状態では扁平状に折り畳むことができる。 <1. Overall configuration of flexible container>
The
コンテナ1に充填される内容物の種類は特に限定されず、典型的には粉粒体や穀物、野菜等である。内容物は、空気中の水分によって性質に影響を受け易いものであってもよく、そのなかでも特に吸水性樹脂粒子が好ましい。
The type of contents to be filled in the container 1 is not particularly limited, and is typically granules, grains, vegetables, or the like. The contents may be those whose properties are easily affected by the moisture in the air, and among them, water-absorbent resin particles are particularly preferable.
フレキシブルコンテナ1は2重構造であり、外袋2と、外袋2内に収容される内袋3とを備える。内容物は、内袋3の内部に充填される。外袋2は、主に強度が高い布を使用した素材を用いてなる。外袋2は、内袋3の大部分を被覆する本体部20を有しており、本体部20は、上面部21と底面部22と側面部23とを有する。本実施形態では、上面部21及び底面部22は、正方形状である。すなわち、外袋2の本体部20は、略直方体形状であり、側面部23は、矩形状の4つの側面を含む。側面部23には、ラベル等を挿入する、透明素材で形成されたポケット23aが取り付けられている。上面部21の中央には、開口(以下、上部開口という)21aが形成されている。また、外袋2は、その底面部22の外面に標識部22aを有しており、本実施形態では、標識部22aとして切欠き穴を採用している。以下、切欠き穴に標識部と同様の符号を付し、切欠き穴22aと称する。切欠き穴22aの詳しい構成については、後述する。
The flexible container 1 has a double structure, and includes an outer bag 2 and an inner bag 3 housed in the outer bag 2. The contents are filled inside the inner bag 3. The outer bag 2 is mainly made of a material using a cloth having high strength. The outer bag 2 has a main body portion 20 that covers most of the inner bag 3, and the main body portion 20 has an upper surface portion 21, a bottom surface portion 22, and a side surface portion 23. In the present embodiment, the upper surface portion 21 and the bottom surface portion 22 have a square shape. That is, the main body portion 20 of the outer bag 2 has a substantially rectangular parallelepiped shape, and the side surface portion 23 includes four rectangular side surfaces. A pocket 23a made of a transparent material into which a label or the like is inserted is attached to the side surface portion 23. An opening (hereinafter referred to as an upper opening) 21a is formed in the center of the upper surface portion 21. Further, the outer bag 2 has a marking portion 22a on the outer surface of the bottom surface portion 22 thereof, and in the present embodiment, a notch hole is adopted as the marking portion 22a. Hereinafter, the notch hole is designated by the same reference numeral as the marking portion and is referred to as the notch hole 22a. The detailed configuration of the notch hole 22a will be described later.
内袋3は、主に樹脂フィルム等の材料からなり、底面部32と側面部33とを有し、上部が開口した略直方体形状である(図2参照)。内袋3の上部は、上部開口21aを介して上面部21の上方へ延出しており、内容物の充填口部31を形成している。内容物は、充填口部31を介して内袋3内に充填される。すなわち、充填口部31は、内容物を内袋3内に充填するための投入路R1を形成する。
The inner bag 3 is mainly made of a material such as a resin film, has a bottom surface portion 32 and a side surface portion 33, and has a substantially rectangular parallelepiped shape with an open upper portion (see FIG. 2). The upper portion of the inner bag 3 extends upward from the upper surface portion 21 through the upper opening 21a, and forms a filling port portion 31 for the contents. The contents are filled in the inner bag 3 via the filling port 31. That is, the filling port portion 31 forms an input path R1 for filling the inner bag 3 with the contents.
内袋3の上下方向の全長は、外袋2の上下方向の全長よりも長く構成される。図2に示すように、内袋3の底面部32は、矩形状であり、底面部32の対向する2辺からは、延端部32aが内袋3の外側に向かってそれぞれ延出している。延端部32aは、外袋2の底面部22と側面部23との間に挟み込まれた状態で、縫い付け等の固定手段により固定されていてもよい。つまり、外袋2と内袋3とは、少なくとも一部において互いに固定されていてもよい。外袋2と内袋3とが固定されている(特に、外袋2と内袋3の底面部32及び/又は底面部32近傍の側面部33とが固定されている)ことで内袋3の切欠き穴22aからの垂下が抑制しやすくなると共に、内容物を充填した状態で内袋3の底面部32が適度に緊張することで破袋具90が貫通しやすくなる。なお、「内袋3が切欠き穴22aから垂下する」とは、コンテナ1を吊り上げた際、内袋3の底面部32が、切欠き穴22aを介して、外袋2の底面部22よりも下方に突出することを意味し、「垂下が抑制される」とは、垂下を完全に防止することのみならず、内袋3の底面部32が外袋2の底面部22よりも下方に突出する程度をフレキシブルコンテナ1の実使用に影響がない程度にまで抑えることも含んでいる。
The total length of the inner bag 3 in the vertical direction is longer than the total length of the outer bag 2 in the vertical direction. As shown in FIG. 2, the bottom surface portion 32 of the inner bag 3 has a rectangular shape, and the extension portion 32a extends toward the outside of the inner bag 3 from the two opposite sides of the bottom surface portion 32. .. The extended end portion 32a may be fixed by a fixing means such as sewing while being sandwiched between the bottom surface portion 22 and the side surface portion 23 of the outer bag 2. That is, the outer bag 2 and the inner bag 3 may be fixed to each other at least in part. The outer bag 2 and the inner bag 3 are fixed (in particular, the bottom surface 32 and / or the side surface 33 near the bottom surface 32 of the outer bag 2 and the inner bag 3 are fixed), so that the inner bag 3 is fixed. The sagging from the notch hole 22a is easily suppressed, and the bottom surface 32 of the inner bag 3 is appropriately tensioned in a state where the contents are filled, so that the bag breaking tool 90 easily penetrates. In addition, "the inner bag 3 hangs down from the notch hole 22a" means that when the container 1 is lifted, the bottom surface portion 32 of the inner bag 3 passes through the notch hole 22a from the bottom surface portion 22 of the outer bag 2. Also means that the hanging is suppressed, and "the hanging is suppressed" not only completely prevents the hanging, but also the bottom surface 32 of the inner bag 3 is below the bottom surface 22 of the outer bag 2. It also includes suppressing the degree of protrusion to the extent that it does not affect the actual use of the flexible container 1.
また、内袋3の延端部32aを外袋2に固定することで内袋3が破れにくくなる上に、内袋3の気密性をより保つことができる。そのため、内袋3には空気中の水分によって性質に影響を受け易い内容物(例えば、吸水性樹脂粒子)を好ましく充填することもできる。
Further, by fixing the extended end portion 32a of the inner bag 3 to the outer bag 2, the inner bag 3 is less likely to be torn, and the airtightness of the inner bag 3 can be further maintained. Therefore, the inner bag 3 can be preferably filled with contents (for example, water-absorbent resin particles) that are easily affected by the moisture in the air.
本実施形態では、図10の断面図に示すように、外袋2の側面部23を内側に折り返し、折り返した部分に外袋2の底面部22と内袋3の延端部32aとを共に挟み込み、さらにこれらを一点鎖線で示す位置で共に縫い付けることにより、外袋2と内袋3とが互いに固定される。なお、延端部32aと底面部22との間には、後述するシート状部材50の端部が配置され、他の部分と共に固定されてもよい。このように、外袋2、内袋3とシート状部材50の固定手段(本実施形態では、縫い付け)を共通させることで、固定部分がより固く変形しにくくなり、シート状部材50の固定部分が破れにくくなる。また、シート状部材50によって内袋3の底面部32が覆われることで、内容物を充填した後のフレキシブルコンテナ1の底面がより平滑に保たれ、後述する破袋具90を狙い通りの位置で貫通させやすくなる。
In the present embodiment, as shown in the cross-sectional view of FIG. 10, the side surface portion 23 of the outer bag 2 is folded inward, and the bottom surface portion 22 of the outer bag 2 and the extended end portion 32a of the inner bag 3 are both folded back in the folded portion. The outer bag 2 and the inner bag 3 are fixed to each other by sandwiching the bags and sewing them together at the positions indicated by the alternate long and short dash lines. An end portion of the sheet-shaped member 50, which will be described later, may be arranged between the extending end portion 32a and the bottom surface portion 22 and may be fixed together with other portions. In this way, by sharing the fixing means (sewn in this embodiment) between the outer bag 2, the inner bag 3 and the sheet-shaped member 50, the fixed portion becomes harder and less likely to be deformed, and the sheet-shaped member 50 is fixed. The part is hard to tear. Further, by covering the bottom surface portion 32 of the inner bag 3 with the sheet-shaped member 50, the bottom surface of the flexible container 1 after filling the contents is kept smoother, and the bag breaking tool 90 described later is positioned as intended. Makes it easier to penetrate.
外袋2は、上部開口21aから上面部21の上方へ延出する筒状の充填口カバー25を有する。充填口カバー25は、上部開口21aを介して上面部21から突出する内袋3の充填口部31を外側から覆うカバーである。充填口カバー25は、縫い付け等の態様で上面部21に固定されており、上部開口21aを規定する縁付近から起立するように配置される。充填口カバー25の断面形状は、上部開口21aと略同サイズの円形状である。
The outer bag 2 has a tubular filling port cover 25 extending upward from the upper opening 21a to the upper surface portion 21. The filling port cover 25 is a cover that covers the filling port portion 31 of the inner bag 3 protruding from the upper surface portion 21 through the upper opening 21a from the outside. The filling port cover 25 is fixed to the upper surface portion 21 in a manner such as sewing, and is arranged so as to stand up from the vicinity of the edge defining the upper opening 21a. The cross-sectional shape of the filling port cover 25 is a circular shape having substantially the same size as the upper opening 21a.
内袋3の上部(充填口部31)の開口面積は、充填口カバー25の開口面積よりも広い。そのため、充填口部31は、外袋2内に収容されたときに皺が形成され、絞られる。以上のとおり、充填口部31は、充填口カバー25とともに充填口を形成するため、以下では、充填口部31及び充填口カバー25を合わせて充填ポートP1と呼ぶことがある。
The opening area of the upper part (filling port portion 31) of the inner bag 3 is wider than the opening area of the filling port cover 25. Therefore, the filling port 31 is wrinkled and squeezed when it is housed in the outer bag 2. As described above, since the filling port portion 31 forms a filling port together with the filling port cover 25, hereinafter, the filling port portion 31 and the filling port cover 25 may be collectively referred to as a filling port P1.
<1-1.充填ポート近傍の構成>
以下、充填ポートP1近傍の構造について説明する。充填ポートP1は、投入路R1を閉じるような閉袋手段によって閉じられる。閉袋手段としては、例えば、充填ポートP1を縛る結束具45が挙げられる。本実施形態では、結束具45は、図1に示すとおり充填口カバー25の外面に固定されている。結束具45は、紐状の部材である。結束具45は、充填ポートP1を縛っていない状態では水平方向に延びるように、充填口カバー25の上下方向の中央付近に縫い付け等の態様で取り付けられている。 <1-1. Configuration near the filling port>
Hereinafter, the structure in the vicinity of the filling port P1 will be described. The filling port P1 is closed by a bag closing means that closes the loading path R1. Examples of the bag closing means include a bindingtool 45 for binding the filling port P1. In the present embodiment, the binding tool 45 is fixed to the outer surface of the filling port cover 25 as shown in FIG. The binding tool 45 is a string-shaped member. The binding tool 45 is attached in a manner such as sewing near the center of the filling port cover 25 in the vertical direction so as to extend in the horizontal direction when the filling port P1 is not bound.

投入路R1を閉じる場合には、まず、充填口部31をこれを覆っている充填口カバー25とともに、投入路R1を閉じるように絞る。その後、この絞られた状態を保つように、充填ポートP1に結束具45が巻き付けられる。このとき、結束具45は、例えば、蝶々結び等の方法で結ばれる。より具体的には、充填口カバー25と充填口部31とを一緒に一重結びで結び、その後、充填口部31の先端が下を向くように、充填口カバー25から突出した充填口部31を一方に折り返し、充填口部31のこの折り返した部分と充填口カバー25とを蝶々結びで結ぶ構成としてもよい。
When closing the input path R1, first, the filling port portion 31 is squeezed together with the filling port cover 25 covering the filling port portion 31 so as to close the input path R1. After that, the binding tool 45 is wound around the filling port P1 so as to maintain this squeezed state. At this time, the binding tool 45 is tied by a method such as a butterfly knot. More specifically, the filling port cover 25 and the filling port portion 31 are tied together with a single knot, and then the filling port portion 31 protruding from the filling port cover 25 so that the tip of the filling port portion 31 faces downward. May be folded back to one side, and the folded portion of the filling port portion 31 and the filling port cover 25 may be tied with a butterfly knot.
外袋2は、上部開口21aを開閉するための花冠状の蓋(以下、花冠蓋という)24を有する。図3は、花冠蓋24を閉じた状態の外袋2の平面図である。花冠蓋24は、複数の花弁状の部位(以下、花弁部という)24aを含む。これらの花弁部24aは、花冠蓋24の閉状態で中心軸A1周りに放射状に配列され、上部開口21aをその中央部を除いて覆う。花弁部24aは、互いに同じ形状を有し、各々略台形状であるが、底辺が上部開口21aの輪郭に対応する円弧状である。すなわち、花弁部24aの底辺は、上面部21において上部開口21aを規定する縁よりも外側の部分に連続している。
The outer bag 2 has a corolla-shaped lid (hereinafter referred to as a corolla lid) 24 for opening and closing the upper opening 21a. FIG. 3 is a plan view of the outer bag 2 with the corolla lid 24 closed. The corolla lid 24 includes a plurality of petal-like portions (hereinafter referred to as petal portions) 24a. These petal portions 24a are arranged radially around the central axis A1 in the closed state of the corolla lid 24, and cover the upper opening 21a except for the central portion thereof. The petal portions 24a have the same shape as each other, and each has a substantially trapezoidal shape, but the base has an arc shape corresponding to the contour of the upper opening 21a. That is, the bottom of the petal portion 24a is continuous with the portion of the upper surface portion 21 outside the edge defining the upper opening 21a.
花冠蓋には開閉手段が設けられており、本実施形態では紐通し通路と該紐通し通路に挿通された紐によって開閉手段が構成されている。具体的には、花弁部24aの内側の端部付近には、中心軸A1に対して周方向に延びる紐通し通路が形成されており、これらの通路に一本の紐24bが挿通されている。紐通し通路に挿通されていない紐24bの両端部は、スライダー24cにより纏められている。そして、このスライダー24cが2本の紐24bの束に沿って移動することにより、花冠蓋24が開閉される。具体的には、紐24bにより形成されるループが小さくなるようにスライダー24cを移動させると、すなわち紐24bを縛ると、花弁部24aが上面部21と同一平面内に広がるように倒れ、図3に示される閉状態となる。一方、紐24bにより形成されるループが大きくなるようにスライダー24cを移動させると、すなわち紐24bを緩めると、図1のように、花弁部24aを上下方向に真っ直ぐ起立させることができる。
The corolla lid is provided with opening / closing means, and in the present embodiment, the opening / closing means is configured by a string passage and a string inserted through the string passage. Specifically, near the inner end of the petal portion 24a, string passages extending in the circumferential direction with respect to the central axis A1 are formed, and one string 24b is inserted through these passages. .. Both ends of the string 24b, which is not inserted into the string passage, are gathered by the slider 24c. Then, the slider 24c moves along the bundle of the two strings 24b, so that the corolla lid 24 is opened and closed. Specifically, when the slider 24c is moved so that the loop formed by the string 24b becomes smaller, that is, when the string 24b is tied, the petal portion 24a collapses so as to spread in the same plane as the upper surface portion 21, and FIG. It becomes the closed state shown in. On the other hand, if the slider 24c is moved so that the loop formed by the string 24b becomes large, that is, if the string 24b is loosened, the petal portion 24a can be erected straight in the vertical direction as shown in FIG.
図1に示すように、充填口カバー25は、花冠蓋24の内側に配置される。すなわち、花冠蓋24は、外側から充填口カバー25を囲むように上面部21に固定されている。また、充填口カバー25の外側であって、花冠蓋24の内側には、内蓋4が配置される。内蓋4も、外側から花冠蓋24に囲まれる。結束具45により縛られた充填ポートP1は、適宜折り畳まれ、花冠蓋24の内側に収容され、その後、花冠蓋24が閉じられる。このとき、内蓋4は、花冠蓋24の内側において充填ポートP1を上側から覆う。なお、花冠蓋24は、図3に示すように完全に閉じられる必要はない。すなわち、充填ポートP1を部分的に、花冠蓋24の中央部に形成される開口24dから突出させてもよい。
As shown in FIG. 1, the filling port cover 25 is arranged inside the corolla lid 24. That is, the corolla lid 24 is fixed to the upper surface portion 21 so as to surround the filling port cover 25 from the outside. Further, the inner lid 4 is arranged outside the filling port cover 25 and inside the corolla lid 24. The inner lid 4 is also surrounded by the corolla lid 24 from the outside. The filling port P1 bound by the binding tool 45 is appropriately folded and housed inside the corolla lid 24, after which the corolla lid 24 is closed. At this time, the inner lid 4 covers the filling port P1 from above inside the corolla lid 24. The corolla lid 24 does not need to be completely closed as shown in FIG. That is, the filling port P1 may partially protrude from the opening 24d formed in the central portion of the corolla lid 24.
<1-2.底面近傍の構成>
次に、コンテナ1の底面近傍の構成について説明する。コンテナ1の底面は、コンテナ1を開袋する際に、コンテナ1の下方に配置された破袋具90が貫通するように構成される。図4に本実施形態に係るコンテナ1の底面図を示す。外袋2は、底面部22の外面に標識部22aを有する。標識部22aは、破袋具90が貫通する位置を示す。従って、標識部22aは、底面部22の外面の他の部分とは区別されるような態様で形成される。本実施形態では、標識部22aは、底面部22の中央部分が切り欠かれて形成された開口(切欠き穴)である。切欠き穴22aは、本実施形態では円形である。なお、本来であれば、図1の側面図には上部開口21a及び切欠き穴22aは現れないが、参考のため、その位置が影により示されている。本体部20、上面部21、底面部22、上部開口21a及び切欠き穴22aは同軸に配置されており、以下、これらに共通する中心軸を符号A1で表す。 <1-2. Configuration near the bottom>
Next, the configuration near the bottom surface of thecontainer 1 will be described. The bottom surface of the container 1 is configured so that the bag breaking tool 90 arranged below the container 1 penetrates when the container 1 is opened. FIG. 4 shows a bottom view of the container 1 according to the present embodiment. The outer bag 2 has a marking portion 22a on the outer surface of the bottom surface portion 22. The marking portion 22a indicates a position through which the bag breaking tool 90 penetrates. Therefore, the marking portion 22a is formed in such a manner that it can be distinguished from other portions on the outer surface of the bottom surface portion 22. In the present embodiment, the marking portion 22a is an opening (notch hole) formed by notching the central portion of the bottom surface portion 22. The notch hole 22a is circular in this embodiment. Originally, the upper opening 21a and the notch hole 22a do not appear in the side view of FIG. 1, but their positions are shown by shadows for reference. The main body portion 20, the upper surface portion 21, the bottom surface portion 22, the upper opening 21a and the notch hole 22a are arranged coaxially, and the central axis common to these is represented by reference numeral A1 below.
次に、コンテナ1の底面近傍の構成について説明する。コンテナ1の底面は、コンテナ1を開袋する際に、コンテナ1の下方に配置された破袋具90が貫通するように構成される。図4に本実施形態に係るコンテナ1の底面図を示す。外袋2は、底面部22の外面に標識部22aを有する。標識部22aは、破袋具90が貫通する位置を示す。従って、標識部22aは、底面部22の外面の他の部分とは区別されるような態様で形成される。本実施形態では、標識部22aは、底面部22の中央部分が切り欠かれて形成された開口(切欠き穴)である。切欠き穴22aは、本実施形態では円形である。なお、本来であれば、図1の側面図には上部開口21a及び切欠き穴22aは現れないが、参考のため、その位置が影により示されている。本体部20、上面部21、底面部22、上部開口21a及び切欠き穴22aは同軸に配置されており、以下、これらに共通する中心軸を符号A1で表す。 <1-2. Configuration near the bottom>
Next, the configuration near the bottom surface of the
本実施形態のコンテナ1は、内容物が充填された内袋3が切欠き穴22aから垂下し内袋3が傷つくことを防止するための、垂下抑制手段を備えている。垂下抑制手段は、例えば切欠き穴22aの少なくとも一部を覆う覆い部材を含むことができる。覆い部材が設置される場所は、外袋2の底面部22の外面及び内面、側面部23の外面及び内面、内袋3の外面、及び外袋2と内袋3との間等、実施の形態に応じて適宜選択することができる。本実施形態では、覆い部材(垂下抑制手段)として、シート状部材50を採用している。具体的には、本実施形態に係るコンテナ1は、外袋2の底面部22と、内袋3の底面部32との間に設置され、切欠き穴22aを覆うシート状部材50をさらに備える。シート状部材50は、本実施形態では、底面部22よりも一回り小さい矩形状であり、切欠き穴22aの全体を外袋2の内側から覆っている。即ち、図4において切欠き穴22aから露出しているのは、内袋3ではなく、シート状部材50である。このように、切欠き穴22aがシート状部材50によって覆われているため、内袋3は切欠き穴22aから露出せず且つ垂下し難い。なお、上述したように外袋2と内袋3とを底面部32の周囲付近で固定することでも、この垂下を低減することができるが、内袋3には柔らかさが求められるため、厚みが制限され、伸びやすく、これだけで垂下を十分に抑制することは難しい。そのため、外袋2と内袋3とを固定していても、シート状部材50のような垂下抑制手段を設けることが好ましい。
The container 1 of the present embodiment is provided with a sagging suppressing means for preventing the inner bag 3 filled with the contents from hanging from the notch hole 22a and damaging the inner bag 3. The droop suppressing means can include, for example, a covering member that covers at least a part of the notch hole 22a. Places where the covering member is installed include the outer and inner surfaces of the bottom surface portion 22 of the outer bag 2, the outer and inner surfaces of the side surface portion 23, the outer surface of the inner bag 3, and between the outer bag 2 and the inner bag 3. It can be appropriately selected according to the form. In the present embodiment, the sheet-shaped member 50 is adopted as the covering member (hanging suppressing means). Specifically, the container 1 according to the present embodiment is further provided with a sheet-like member 50 which is installed between the bottom surface portion 22 of the outer bag 2 and the bottom surface portion 32 of the inner bag 3 and covers the notch hole 22a. .. In the present embodiment, the sheet-shaped member 50 has a rectangular shape that is one size smaller than the bottom surface portion 22, and covers the entire notch hole 22a from the inside of the outer bag 2. That is, what is exposed from the notch hole 22a in FIG. 4 is not the inner bag 3 but the sheet-shaped member 50. Since the notch hole 22a is covered with the sheet-like member 50 in this way, the inner bag 3 is not exposed from the notch hole 22a and is difficult to hang down. Although the sagging can be reduced by fixing the outer bag 2 and the inner bag 3 near the periphery of the bottom surface portion 32 as described above, the inner bag 3 is required to be soft, so that the thickness of the inner bag 3 is required. Is restricted and easily stretched, and it is difficult to sufficiently suppress drooping by this alone. Therefore, even if the outer bag 2 and the inner bag 3 are fixed, it is preferable to provide a sagging suppressing means such as a sheet-shaped member 50.
切欠き穴22aの面積は、破袋具90の位置合わせを容易にすることを考慮し、外袋2の底面部22の面積(切欠き穴22aを含む面積)の5%以上、10%以上、又は15%以上であることが好ましい。また、切欠き穴22aの面積は、内袋3の垂下を抑制し易くするため、外袋2の底面部22の面積(切欠き穴22aを含む面積)の30%以下、25%以下、又は20%以下であることが好ましい。
The area of the notch hole 22a is 5% or more and 10% or more of the area of the bottom surface portion 22 of the outer bag 2 (the area including the notch hole 22a) in consideration of facilitating the alignment of the bag breaking tool 90. , Or 15% or more is preferable. Further, the area of the notch hole 22a is 30% or less, 25% or less, or 25% or less of the area of the bottom surface portion 22 of the outer bag 2 (the area including the notch hole 22a) in order to easily suppress the hanging of the inner bag 3. It is preferably 20% or less.
シート状部材50は、コンテナ1の輸送時や吊り下げ時に、内袋3が内容物の質量によって切欠き穴22aから垂下することを抑制するのみならず、切欠き穴22aから内袋3が露出することを防止することができる。シート状部材50は、外袋2の柔軟性を妨げない程度の柔軟性を有するとともに、内袋3と比較して大きく変形しない素材から構成されることが好ましい。また、シート状部材50は、コンテナ1の開袋時に内袋3と共に破袋具90によって切り開かれる。従って、シート状部材50は、破袋具90によって切り開くことが可能な素材で形成される。
The sheet-shaped member 50 not only prevents the inner bag 3 from hanging from the notch hole 22a due to the mass of the contents when the container 1 is transported or suspended, but also exposes the inner bag 3 from the notch hole 22a. It can be prevented from doing so. The sheet-shaped member 50 is preferably made of a material that has flexibility that does not hinder the flexibility of the outer bag 2 and does not deform significantly as compared with the inner bag 3. Further, the sheet-shaped member 50 is cut open by the bag breaking tool 90 together with the inner bag 3 when the container 1 is opened. Therefore, the sheet-shaped member 50 is made of a material that can be cut open by the bag breaking tool 90.
シート状部材50を構成する材料は、コンテナ1の内容物及び選択する内袋3によって適宜変更することができるが、破袋具90によって切り開き易いだけでなく、内容物が吸水性樹脂粒子である場合などはその物性が変化しないようある程度の不透湿性を有する材料であることが望ましい。このような材料としては、合成樹脂が挙げられ、具体的には、ポリエチレン、ポリプロピレン、環状オレフィン、ポリエチレンを含む共重合ポリマーなどのポリオレフィン系樹脂;ポリエチレンテレフタレート、ポリ乳酸などのポリエステル系樹脂;ポリアミド系樹脂;ポリスチレン系樹脂などが挙げられる。シート状部材50の材料として、好ましくはポリオレフィン系樹脂であり、より好ましくはポリエチレン又はポリプロピレンである。シート状部材50が裂けやすい材料であると外部からのキズによって意図せずシート状部材50に大きな穴が開き、結果として穴から露出した内袋3が破袋してしまう可能性もあるが、ポリエチレンやポリプロピレン(特にポリエチレン)であれば、シート状部材50に小さなキズが入ったとしても大きく穴が開くまで至らず、内袋3の破袋を防ぐことができる。
The material constituting the sheet-shaped member 50 can be appropriately changed depending on the contents of the container 1 and the inner bag 3 to be selected, but not only is it easy to cut open by the bag breaking tool 90, but the contents are water-absorbent resin particles. In some cases, it is desirable that the material has a certain degree of impermeable property so that its physical properties do not change. Examples of such a material include synthetic resins, and specifically, polyolefin resins such as polyethylene, polypropylene, cyclic olefins, and copolymer polymers containing polyethylene; polyester resins such as polyethylene terephthalate and polylactic acid; polyamide resins. Resin: Polyethylene-based resin and the like can be mentioned. The material of the sheet-shaped member 50 is preferably a polyolefin resin, and more preferably polyethylene or polypropylene. If the sheet-shaped member 50 is made of a material that is easily torn, a large hole may be unintentionally opened in the sheet-shaped member 50 due to an external scratch, and as a result, the inner bag 3 exposed from the hole may be torn. In the case of polyethylene or polypropylene (particularly polyethylene), even if a small scratch is made on the sheet-shaped member 50, it does not reach a large hole, and the inner bag 3 can be prevented from being broken.
また、シート状部材50の厚みは、コンテナ1の内容物に応じて、適宜選択することができる。内容物が吸水性樹脂粒子である場合、シート状部材50の厚みは、破袋具90によって切り開き易く、内袋3の垂下を十分に抑制でき、且つ、吸水性樹脂粒子の物性が変化しないようある程度の不透湿性を担保できる範囲であることが望ましい。これらを考慮すると、具体的なシート状部材50の厚みは、その下限値が、例えば50μm、好ましくは80μm、より好ましくは100μm、特に好ましくは120μmであり、その上限値は、例えば500μm、好ましくは300μm、より好ましくは200μmである。
Further, the thickness of the sheet-shaped member 50 can be appropriately selected according to the contents of the container 1. When the content is water-absorbent resin particles, the thickness of the sheet-like member 50 is easily cut open by the bag-breaking tool 90, the sagging of the inner bag 3 can be sufficiently suppressed, and the physical properties of the water-absorbent resin particles do not change. It is desirable that the range is such that a certain degree of impermeable property can be guaranteed. In consideration of these, the lower limit of the thickness of the specific sheet-shaped member 50 is, for example, 50 μm, preferably 80 μm, more preferably 100 μm, particularly preferably 120 μm, and the upper limit thereof is, for example, 500 μm, preferably 120 μm. It is 300 μm, more preferably 200 μm.
<1-3.その他の構成>
コンテナ1は、外袋2に固定されている複数の被引っ掛け具35bをさらに備える。被引っ掛け具35bは、フレキシブルコンテナ1を上方から吊り下げる吊り具7に引っ掛けるための部材である。被引っ掛け具35bは、外袋2の側面部23の幅方向中央付近に配置される紐状の部材(以下、枠紐という)35の上部に対応する。より具体的には、図1に示すように側面部23の幅方向中央付近であって、ポケット23aよりも上部には、2本の枠紐35の端部35aが、互いに重ねられて縫い付け等の態様で固定される。1本の枠紐35は、上部が上面部21の四隅を跨いで、端部35aが隣り合う側面部23に固定される(図3参照)。これにより、枠紐35の上部は、ループ状を維持するように形成され、これが被引っ掛け具35bとなる。 <1-3. Other configurations>
Thecontainer 1 further includes a plurality of hooking tools 35b fixed to the outer bag 2. The hooked tool 35b is a member for hooking the flexible container 1 on the hanging tool 7 that is suspended from above. The hooked tool 35b corresponds to the upper portion of a string-shaped member (hereinafter, referred to as a frame string) 35 arranged near the center in the width direction of the side surface portion 23 of the outer bag 2. More specifically, as shown in FIG. 1, the end portions 35a of the two frame cords 35 are sewn on top of each other near the center of the side surface portion 23 in the width direction and above the pocket 23a. It is fixed in such an manner. The upper portion of one frame string 35 straddles the four corners of the upper surface portion 21, and the end portions 35a are fixed to the adjacent side surface portions 23 (see FIG. 3). As a result, the upper portion of the frame string 35 is formed so as to maintain the loop shape, and this becomes the hooked tool 35b.
コンテナ1は、外袋2に固定されている複数の被引っ掛け具35bをさらに備える。被引っ掛け具35bは、フレキシブルコンテナ1を上方から吊り下げる吊り具7に引っ掛けるための部材である。被引っ掛け具35bは、外袋2の側面部23の幅方向中央付近に配置される紐状の部材(以下、枠紐という)35の上部に対応する。より具体的には、図1に示すように側面部23の幅方向中央付近であって、ポケット23aよりも上部には、2本の枠紐35の端部35aが、互いに重ねられて縫い付け等の態様で固定される。1本の枠紐35は、上部が上面部21の四隅を跨いで、端部35aが隣り合う側面部23に固定される(図3参照)。これにより、枠紐35の上部は、ループ状を維持するように形成され、これが被引っ掛け具35bとなる。 <1-3.

図5に、吊り具7に被引っ掛け具35bが引っ掛けられて上方から吊り下げられたコンテナ1の様子を示す。図5に示すように、例えば上方から下がる4つの吊り具7に、被引っ掛け具35bをそれぞれ引っ掛けることより、フレキシブルコンテナ1を上方から吊り下げることができる。なお、吊り具7は、典型的には、フックである。
FIG. 5 shows a state of the container 1 in which the hooked tool 35b is hooked on the hanging tool 7 and suspended from above. As shown in FIG. 5, for example, the flexible container 1 can be hung from above by hooking the hooked tool 35b on each of the four hanging tools 7 that hang from above. The hanging tool 7 is typically a hook.

<2-1.フレキシブルコンテナの充填方法>
まず、外袋2、内袋3及びシート状部材50を用意する。外袋2内に、底面部22に沿うようにシート状部材50を収容し、切欠き穴22aを内側から覆う。続いて、外袋2内に内袋3を収容する。内袋3は、底面部32がシート状部材50の上面に沿い、側面部33が側面部23の内面に沿うように収容される。そして、内袋3の上部の充填口部31を、外袋2の上面部21の上部開口21a及び充填口カバー25に挿入し、充填口カバー25の上端からやや露出するように引き出す。これにより、上部開口21aを介して上面部21の上方へ突出した充填口部31と、充填口カバー25とにより、充填ポートP1が形成される。 <2-1. Flexible container filling method>
First, theouter bag 2, the inner bag 3, and the sheet-shaped member 50 are prepared. A sheet-shaped member 50 is housed in the outer bag 2 along the bottom surface portion 22, and the notch hole 22a is covered from the inside. Subsequently, the inner bag 3 is housed in the outer bag 2. The inner bag 3 is accommodated so that the bottom surface portion 32 is along the upper surface of the sheet-like member 50 and the side surface portion 33 is along the inner surface of the side surface portion 23. Then, the filling port 31 at the upper part of the inner bag 3 is inserted into the upper opening 21a and the filling port cover 25 of the upper surface portion 21 of the outer bag 2 and pulled out so as to be slightly exposed from the upper end of the filling port cover 25. As a result, the filling port P1 is formed by the filling port portion 31 protruding upward from the upper surface portion 21 through the upper opening 21a and the filling port cover 25.
まず、外袋2、内袋3及びシート状部材50を用意する。外袋2内に、底面部22に沿うようにシート状部材50を収容し、切欠き穴22aを内側から覆う。続いて、外袋2内に内袋3を収容する。内袋3は、底面部32がシート状部材50の上面に沿い、側面部33が側面部23の内面に沿うように収容される。そして、内袋3の上部の充填口部31を、外袋2の上面部21の上部開口21a及び充填口カバー25に挿入し、充填口カバー25の上端からやや露出するように引き出す。これにより、上部開口21aを介して上面部21の上方へ突出した充填口部31と、充填口カバー25とにより、充填ポートP1が形成される。 <2-1. Flexible container filling method>
First, the
続いて、上記のようにして準備された空のフレキシブルコンテナ1に内容物を充填する。まず、空のコンテナ1を、内容物を供給するホッパー等の装置(以下、供給装置という)の下方に、上面部21が上を向くような態勢で配置する。次に、外袋2の被引っ掛け具35bを供給装置のフック等の吊り具にそれぞれ引っ掛け、フレキシブルコンテナ1を上方から吊り下げる。そして、スライダー24cを緩め花冠蓋24を開くとともに、内蓋4も開き、さらに充填ポートP1をできる限り大きく筒状に開く。続いて、供給装置の排出口を投入路R1に挿入する。このとき、充填ポートP1は、供給装置の排出口を覆うように、供給装置に冶具等で固定されていてもよい。これにより、投入路R1が上方に向かって、すなわち、供給装置において内容物を排出する排出口に向かって大きく開かれる。続いて、供給装置の排出口を開くことにより、投入路R1を介して内袋3内へと供給装置から内容物が投入される。
Subsequently, the contents are filled in the empty flexible container 1 prepared as described above. First, the empty container 1 is arranged below a device such as a hopper for supplying the contents (hereinafter referred to as a supply device) so that the upper surface portion 21 faces upward. Next, the hooked tool 35b of the outer bag 2 is hooked on a hanging tool such as a hook of the supply device, and the flexible container 1 is hung from above. Then, the slider 24c is loosened to open the corolla lid 24, the inner lid 4 is also opened, and the filling port P1 is opened as large as possible in a tubular shape. Subsequently, the discharge port of the supply device is inserted into the input path R1. At this time, the filling port P1 may be fixed to the supply device with a jig or the like so as to cover the discharge port of the supply device. As a result, the input path R1 is wide open upward, that is, toward the discharge port for discharging the contents in the supply device. Subsequently, by opening the discharge port of the supply device, the contents are charged from the supply device into the inner bag 3 via the input path R1.
内容物の充填後、充填ポートP1を閉じる。具体的には、充填口部31の内側に形成される投入路R1を閉じるように、充填ポートP1を絞る。そして、細長くなった充填ポートP1を外側から囲むように、これに結束具45を強く巻き付けた後、結束具45を結んで巻き付け状態をロックする。続いて、充填ポートP1を折り畳み、その上に内蓋4を載せ、さらに花冠蓋24を閉じる。これにより、上部開口21aが閉じられ、充填ポートP1が花冠蓋24の内側に収容される。以上により、内容物入りのフレキシブルコンテナ1が製造される。
After filling the contents, close the filling port P1. Specifically, the filling port P1 is narrowed down so as to close the input path R1 formed inside the filling port portion 31. Then, the binding tool 45 is tightly wound around the elongated filling port P1 so as to surround it from the outside, and then the binding tool 45 is tied to lock the wound state. Subsequently, the filling port P1 is folded, the inner lid 4 is placed on the filling port P1, and the corolla lid 24 is further closed. As a result, the upper opening 21a is closed and the filling port P1 is housed inside the corolla lid 24. As described above, the flexible container 1 containing the contents is manufactured.
内容物入りのフレキシブルコンテナ1は、適当な保管場所に保管され、必要に応じて輸送される。輸送時等、フレキシブルコンテナ1を移動させる際には、パレットに載せこれをフォークリフト等の搬送装置で運搬することができる。また、フック等の吊り具を有するクレーン等の搬送装置を利用することができる。すなわち、被引っ掛け具35bを搬送装置の吊り具に引っ掛けた状態で搬送装置を駆動することにより、フレキシブルコンテナ1を容易に移動させることができる。
The flexible container 1 containing the contents is stored in an appropriate storage location and transported as needed. When moving the flexible container 1 during transportation or the like, it can be placed on a pallet and transported by a transport device such as a forklift. Further, a transport device such as a crane having a hanging tool such as a hook can be used. That is, the flexible container 1 can be easily moved by driving the transfer device in a state where the hooked tool 35b is hooked on the hanging tool of the transfer device.
<2-2.フレキシブルコンテナの開袋方法>
次に、内容物入りのフレキシブルコンテナ1の開袋方法について図6に示す例を参照しつつ説明する。まず、内容物入りのコンテナ1を、内容物が供給されるホッパー等の装置(以下、被供給装置91という)の上方に、底面部22が下を向くような態勢で配置する。コンテナ1の配置方法は、特に限定されない。例えば、上方から下がる可動式の4つの吊り具7aにコンテナ1の被引っ掛け具35bをそれぞれ引っ掛けた状態でコンテナ1を吊り上げた後、吊り具7aを移動させ、被供給装置91の上方にコンテナ1を配置することができる。図6に示す例では、吊り具7aは図6の上下方向、左右方向及び紙面方向に移動することができる。 <2-2. How to open a flexible container >
Next, a method of opening theflexible container 1 containing the contents will be described with reference to the example shown in FIG. First, the container 1 containing the contents is arranged above a device such as a hopper to which the contents are supplied (hereinafter referred to as a supplied device 91) so that the bottom surface portion 22 faces downward. The method of arranging the container 1 is not particularly limited. For example, after lifting the container 1 in a state where the hooked tool 35b of the container 1 is hooked on each of the four movable hanging tools 7a that are lowered from above, the hanging tool 7a is moved and the container 1 is moved above the supplied device 91. Can be placed. In the example shown in FIG. 6, the hanger 7a can move in the vertical direction, the horizontal direction, and the paper surface direction of FIG.
次に、内容物入りのフレキシブルコンテナ1の開袋方法について図6に示す例を参照しつつ説明する。まず、内容物入りのコンテナ1を、内容物が供給されるホッパー等の装置(以下、被供給装置91という)の上方に、底面部22が下を向くような態勢で配置する。コンテナ1の配置方法は、特に限定されない。例えば、上方から下がる可動式の4つの吊り具7aにコンテナ1の被引っ掛け具35bをそれぞれ引っ掛けた状態でコンテナ1を吊り上げた後、吊り具7aを移動させ、被供給装置91の上方にコンテナ1を配置することができる。図6に示す例では、吊り具7aは図6の上下方向、左右方向及び紙面方向に移動することができる。 <2-2. How to open a flexible container >
Next, a method of opening the
図6に示す被供給装置91の中央部の上方には、破袋具90が固定されている。破袋具90は、典型的には刃物であり、刃先が上方に向いた状態で固定される。破袋具90は、外袋2の標識部と、内袋3の底面部32とを共に貫通するように構成される。本実施形態では、破袋具90は、シート状部材50及び内袋3の底面部32を共に貫通するように構成される。従って、コンテナ1は、破袋具90の刃先が外袋2の底面部22の、切欠き穴22aを規定する円形の周縁の内側に位置するように位置合わせされる(なお、参考のために、図6には切欠き穴22aの位置が影により示されている)。言い換えると、コンテナ1は、シート状部材50のうち、切欠き穴22aから露出している部分を破袋具90が貫通するように位置合わせされる。コンテナ1の位置合わせは、例えば標識部である切欠き穴22aの位置を確認しつつ、作業員の目視で行われてもよい。また、破袋具90の付近に設置されたカメラにより撮像される映像を、遠隔のモニターにより確認しながら行われてもよい。
A bag breaking tool 90 is fixed above the central portion of the supplied device 91 shown in FIG. The bag breaking tool 90 is typically a cutting tool, and is fixed with the cutting edge facing upward. The bag breaking tool 90 is configured to penetrate both the marking portion of the outer bag 2 and the bottom surface portion 32 of the inner bag 3. In the present embodiment, the bag breaking tool 90 is configured to penetrate both the sheet-like member 50 and the bottom surface portion 32 of the inner bag 3. Therefore, the container 1 is aligned so that the cutting edge of the bag breaking tool 90 is located inside the circular peripheral edge of the bottom surface portion 22 of the outer bag 2 that defines the notch hole 22a (for reference). , The position of the notch hole 22a is shown by a shadow in FIG. 6). In other words, the container 1 is aligned so that the bag breaking tool 90 penetrates the portion of the sheet-shaped member 50 exposed from the notch hole 22a. The alignment of the container 1 may be performed visually by an operator while checking the position of the notch hole 22a, which is a sign portion, for example. In addition, the image captured by the camera installed near the bag breaking tool 90 may be confirmed by a remote monitor.
次に、吊り具7aを全て図6の下方向に移動させ、コンテナ1の内袋3の底面部32が破袋具90の刃先よりも下方に位置するようにする。このとき、破袋具90の刃先が切欠き穴22aから露出しているシート状部材50と、内袋3の底面部32とを貫通する。これにより、内袋3内に充填された内容物が破袋具90の周囲を介して、被供給装置91へと排出される。
Next, all the hanging tools 7a are moved downward in FIG. 6 so that the bottom surface 32 of the inner bag 3 of the container 1 is located below the cutting edge of the bag breaking tool 90. At this time, the cutting edge of the bag breaking tool 90 penetrates the sheet-like member 50 exposed from the notch hole 22a and the bottom surface portion 32 of the inner bag 3. As a result, the contents filled in the inner bag 3 are discharged to the supplied device 91 via the periphery of the bag breaking tool 90.

上記実施形態では、外袋2の本体部20及び内袋3は略直方体形状とされたが、これに限られず、例えば、円筒状とすることもできる。 <3-1>
In the above embodiment, themain body 20 and the inner bag 3 of the outer bag 2 have a substantially rectangular parallelepiped shape, but the present invention is not limited to this, and for example, the inner bag 3 may have a cylindrical shape.
上記実施形態では、外袋2の本体部20及び内袋3は略直方体形状とされたが、これに限られず、例えば、円筒状とすることもできる。 <3-1>
In the above embodiment, the
<3-2>
標識部22aの態様は、切欠き穴に限定されない。例えば、図7Aに示すように、底面部22の外面に表示される模様とすることもできる。模様の形成方法は、実施の形態に合わせて適宜選択することができる。例えば、底面部22にインク等によって描かれたり、底面部22の一部において、外袋2を構成する布等の素材の織り方を変えたりする等の態様によって形成されてもよい。 <3-2>
The aspect of the markingportion 22a is not limited to the notch hole. For example, as shown in FIG. 7A, the pattern may be displayed on the outer surface of the bottom surface portion 22. The pattern forming method can be appropriately selected according to the embodiment. For example, it may be drawn on the bottom surface portion 22 with ink or the like, or may be formed on a part of the bottom surface portion 22 by changing the weaving method of a material such as a cloth constituting the outer bag 2.
標識部22aの態様は、切欠き穴に限定されない。例えば、図7Aに示すように、底面部22の外面に表示される模様とすることもできる。模様の形成方法は、実施の形態に合わせて適宜選択することができる。例えば、底面部22にインク等によって描かれたり、底面部22の一部において、外袋2を構成する布等の素材の織り方を変えたりする等の態様によって形成されてもよい。 <3-2>
The aspect of the marking
<3-3>
切欠き穴22aの構成は、上述したもの(1つの貫通穴)に限られない。例えば、図7Bに示すように、底面部22に略半円形状の貫通穴が2つ形成される構成とすることもできる。このような構成では、2つの貫通穴を区画する(境界を規定する)帯状部22dが、切欠き穴22aから内袋3が垂下するのを抑制する垂下抑制手段として機能することができる。帯状部22dは、2つの貫通穴を作成した際に残留する底面部22の一部であってもよく(この場合、帯状部22dの素材は必然的に底面部22と同一である)、1つの貫通穴を形成した後、外袋2とは別体である帯状の部材を、該貫通穴の一部を覆うように取り付けることで形成されてもよい(この場合、帯状部22dの素材は底面部22と同一であってもよく異なっていてもよい)。 <3-3>
The configuration of thenotch hole 22a is not limited to that described above (one through hole). For example, as shown in FIG. 7B, two substantially semicircular through holes may be formed in the bottom surface portion 22. In such a configuration, the band-shaped portion 22d that separates the two through holes (defines the boundary) can function as a hanging suppressing means for suppressing the inner bag 3 from hanging from the notch hole 22a. The band-shaped portion 22d may be a part of the bottom surface portion 22 that remains when the two through holes are created (in this case, the material of the strip-shaped portion 22d is necessarily the same as the bottom surface portion 22), 1 After forming the two through holes, a band-shaped member that is separate from the outer bag 2 may be attached so as to cover a part of the through holes (in this case, the material of the band-shaped portion 22d is It may be the same as or different from the bottom surface portion 22).
切欠き穴22aの構成は、上述したもの(1つの貫通穴)に限られない。例えば、図7Bに示すように、底面部22に略半円形状の貫通穴が2つ形成される構成とすることもできる。このような構成では、2つの貫通穴を区画する(境界を規定する)帯状部22dが、切欠き穴22aから内袋3が垂下するのを抑制する垂下抑制手段として機能することができる。帯状部22dは、2つの貫通穴を作成した際に残留する底面部22の一部であってもよく(この場合、帯状部22dの素材は必然的に底面部22と同一である)、1つの貫通穴を形成した後、外袋2とは別体である帯状の部材を、該貫通穴の一部を覆うように取り付けることで形成されてもよい(この場合、帯状部22dの素材は底面部22と同一であってもよく異なっていてもよい)。 <3-3>
The configuration of the
<3-4>
切欠き穴22aから内袋3が垂下することを抑制する垂下抑制手段は、上述したシート状部材50に限定されず、実施の形態に応じて適宜選択することができる。例えば、コンテナ1は、図7Cに示すように、覆い部材として切欠き穴22aの一部を覆う紐状の部材51を備えてもよい。紐状の部材51は、縫い付け等の固定手段によって、例えば外袋2の側面部23に、底面部22の外面に沿うように固定されてもよい。このような構成によれば、底面部22の強度を向上させることができる。また、これに加えて、切欠き穴22aの周囲においてさらに縫い付け等の固定手段により固定されてもよい。このような構成によれば、破袋具90によって紐状の部材51が切断されたとしても、紐状の部材51の破片が底面部22から離れて取り出された内容物に混入することが抑制される。以上の構成は、あくまで例示であり、紐状の部材51の素材及び数、固定手段、固定位置等は、適宜選択することができる。 <3-4>
The sagging suppressing means for suppressing the sagging of theinner bag 3 from the notch hole 22a is not limited to the sheet-shaped member 50 described above, and can be appropriately selected depending on the embodiment. For example, as shown in FIG. 7C, the container 1 may include a string-shaped member 51 that covers a part of the notch hole 22a as a covering member. The string-shaped member 51 may be fixed to the side surface portion 23 of the outer bag 2, for example, along the outer surface of the bottom surface portion 22 by a fixing means such as sewing. According to such a configuration, the strength of the bottom surface portion 22 can be improved. In addition to this, it may be further fixed around the notch hole 22a by a fixing means such as sewing. According to such a configuration, even if the string-shaped member 51 is cut by the bag-breaking tool 90, it is possible to prevent the fragments of the string-shaped member 51 from being mixed into the contents taken out from the bottom surface portion 22. Will be done. The above configuration is merely an example, and the material and number of the string-shaped member 51, the fixing means, the fixing position, and the like can be appropriately selected.
切欠き穴22aから内袋3が垂下することを抑制する垂下抑制手段は、上述したシート状部材50に限定されず、実施の形態に応じて適宜選択することができる。例えば、コンテナ1は、図7Cに示すように、覆い部材として切欠き穴22aの一部を覆う紐状の部材51を備えてもよい。紐状の部材51は、縫い付け等の固定手段によって、例えば外袋2の側面部23に、底面部22の外面に沿うように固定されてもよい。このような構成によれば、底面部22の強度を向上させることができる。また、これに加えて、切欠き穴22aの周囲においてさらに縫い付け等の固定手段により固定されてもよい。このような構成によれば、破袋具90によって紐状の部材51が切断されたとしても、紐状の部材51の破片が底面部22から離れて取り出された内容物に混入することが抑制される。以上の構成は、あくまで例示であり、紐状の部材51の素材及び数、固定手段、固定位置等は、適宜選択することができる。 <3-4>
The sagging suppressing means for suppressing the sagging of the
さらに、垂下抑制手段の一例を図8Aに示す。図8Aは、外袋2の底面部22の内面を透視した様子を示している。図8Aに示す例では、底面部22の内面に、内袋3の底面部32に向かって突出する環状の凸部22bが、切欠き穴22aを規定する周縁に沿って形成されている。凸部22bは、内袋3内に充填された内容物が、内袋3と共に切欠き穴22aへと入り込む力に対する抵抗の役割を果たす。凸部22bは、外袋2の底面部22と一体的に形成されてもよいし、外袋2とは別体として形成された後に、底面部22に固定されてもよい。また、凸部22bは、必ずしも切欠き穴22aの周縁全体を囲むように形成されていなくてもよい。つまり、切欠き穴22aの周縁に沿って、部分的に凸部22bが形成されてもよい。
Further, an example of the droop suppressing means is shown in FIG. 8A. FIG. 8A shows a state in which the inner surface of the bottom surface portion 22 of the outer bag 2 is seen through. In the example shown in FIG. 8A, an annular convex portion 22b protruding toward the bottom surface portion 32 of the inner bag 3 is formed on the inner surface of the bottom surface portion 22 along the peripheral edge defining the notch hole 22a. The convex portion 22b serves as a resistance against a force that the contents filled in the inner bag 3 enter into the notch hole 22a together with the inner bag 3. The convex portion 22b may be formed integrally with the bottom surface portion 22 of the outer bag 2, or may be fixed to the bottom surface portion 22 after being formed as a separate body from the outer bag 2. Further, the convex portion 22b does not necessarily have to be formed so as to surround the entire peripheral edge of the notch hole 22a. That is, the convex portion 22b may be partially formed along the peripheral edge of the notch hole 22a.
さらに、垂下抑制手段の一例を図8B及びCに示す。図8Bは、外袋2の底面部22の断面図であり、図8Cは、外袋2の底面図である。図8B及びCに示す例では、底面部22の外面に、複数の受け部22cが、切欠き穴22aを規定する周縁に沿って形成されている。受け部22cは、内袋3の一部が切欠き穴22aから垂下した場合に内袋3を受け止める役割を果たす。受け部22cは、外袋2の底面部22と一体的に形成されてもよいし、外袋2とは別体として形成された後に、底面部22に固定されてもよい。また、受け部22cは、必ずしも切欠き穴22aの周縁全体を囲むように形成されていなくてもよい。つまり、切欠き穴22aの周縁に沿って、部分的に受け部22cが形成されてもよい。
Further, an example of the droop suppressing means is shown in FIGS. 8B and 8C. FIG. 8B is a cross-sectional view of the bottom surface portion 22 of the outer bag 2, and FIG. 8C is a bottom view of the outer bag 2. In the example shown in FIGS. 8B and 8C, a plurality of receiving portions 22c are formed on the outer surface of the bottom surface portion 22 along the peripheral edge defining the notch hole 22a. The receiving portion 22c serves to receive the inner bag 3 when a part of the inner bag 3 hangs down from the notch hole 22a. The receiving portion 22c may be formed integrally with the bottom surface portion 22 of the outer bag 2, or may be fixed to the bottom surface portion 22 after being formed as a separate body from the outer bag 2. Further, the receiving portion 22c does not necessarily have to be formed so as to surround the entire peripheral edge of the notch hole 22a. That is, the receiving portion 22c may be partially formed along the peripheral edge of the notch hole 22a.

In the above embodiment, the
<3-6>
シート状部材50は、外袋2及び内袋3のいずれか一方、又は外袋2及び内袋3の双方に対し少なくとも部分的に固定されていてもよい。この構成によれば、シート状部材50が外袋2内でずれたり、よれて一方向に偏ったりすることを防止することができる。シート状部材50が外袋2及び内袋3の双方に対し固定される場合は、例えば上述したようにシート状部材50の端部を図10に示すように配置した後、縫い付け等の固定手段により固定することができる。 <3-6>
The sheet-shapedmember 50 may be at least partially fixed to either one of the outer bag 2 and the inner bag 3 or both of the outer bag 2 and the inner bag 3. According to this configuration, it is possible to prevent the sheet-shaped member 50 from being displaced or twisted in the outer bag 2 and being biased in one direction. When the sheet-shaped member 50 is fixed to both the outer bag 2 and the inner bag 3, for example, after arranging the end portions of the sheet-shaped member 50 as shown in FIG. 10 as described above, fixing such as sewing or the like is performed. It can be fixed by means.
シート状部材50は、外袋2及び内袋3のいずれか一方、又は外袋2及び内袋3の双方に対し少なくとも部分的に固定されていてもよい。この構成によれば、シート状部材50が外袋2内でずれたり、よれて一方向に偏ったりすることを防止することができる。シート状部材50が外袋2及び内袋3の双方に対し固定される場合は、例えば上述したようにシート状部材50の端部を図10に示すように配置した後、縫い付け等の固定手段により固定することができる。 <3-6>
The sheet-shaped
<3-7>
シート状部材50の構成は、上述のものに限られない。例えば、シート状部材50の形状は矩形状に限られず、円形や十字形等、適宜選択することができる。さらに、シート状部材50は、凹凸が形成された凹凸面50aを有していてもよい。凹凸面50aを内袋3の底面部32に向けてシート状部材50を設置することで、内袋3とシート状部材50との間に摩擦が生じ、内袋3が外袋2内で移動したり、一方向に偏ったりすることを防止することができる。凹凸の断面形状は、例えば図9Aや図9Bに示すように、適宜選択することができる。 <3-7>
The configuration of the sheet-shapedmember 50 is not limited to the above. For example, the shape of the sheet-shaped member 50 is not limited to a rectangular shape, and a circular shape, a cross shape, or the like can be appropriately selected. Further, the sheet-like member 50 may have an uneven surface 50a on which unevenness is formed. By installing the sheet-shaped member 50 with the uneven surface 50a facing the bottom surface 32 of the inner bag 3, friction is generated between the inner bag 3 and the sheet-shaped member 50, and the inner bag 3 moves in the outer bag 2. It is possible to prevent the bag from being biased in one direction. The cross-sectional shape of the unevenness can be appropriately selected as shown in FIGS. 9A and 9B, for example.
シート状部材50の構成は、上述のものに限られない。例えば、シート状部材50の形状は矩形状に限られず、円形や十字形等、適宜選択することができる。さらに、シート状部材50は、凹凸が形成された凹凸面50aを有していてもよい。凹凸面50aを内袋3の底面部32に向けてシート状部材50を設置することで、内袋3とシート状部材50との間に摩擦が生じ、内袋3が外袋2内で移動したり、一方向に偏ったりすることを防止することができる。凹凸の断面形状は、例えば図9Aや図9Bに示すように、適宜選択することができる。 <3-7>

In the above embodiment, when thecontainer 1 is opened, the marking portion (notch hole 22a) of the container 1 is aligned with the cutting edge of the bag breaking tool 90, and the bottom surface portion 32 of the inner bag 3 is the bag breaking tool 90. The bag breaking tool 90 penetrates the container 1 so as to be located below the cutting edge of the container 1. However, the method of opening the container 1 is not limited to this. For example, the container 1 may be arranged above the device to be supplied 91, and the cutting edge of the bag breaking tool 90 may be aligned with the marking portion of the container 1. Further, the bag breaking tool 90 is moved upward with respect to the container 1, and the bag breaking tool 90 penetrates the container 1 so that the cutting edge of the bag breaking tool 90 is located above the bottom surface portion 32 of the inner bag 3. You may do so.
上記実施形態では、コンテナ1の開袋の際に破袋具90の刃先に対してコンテナ1の標識部(切欠き穴22a)を位置合わせし、内袋3の底面部32が破袋具90の刃先よりも下方に位置するようにして破袋具90がコンテナ1を貫通するようにした。しかしながら、コンテナ1の開袋方法はこれに限定されない。例えば、コンテナ1を被供給装置91の上方に配置し、破袋具90の刃先をコンテナ1の標識部に対して位置合わせしてもよい。また、コンテナ1に対して破袋具90を上方に移動させ、破袋具90の刃先が内袋3の底面部32よりも上方に位置するようにして破袋具90がコンテナ1を貫通するようにしてもよい。 <3-8>

The means for fixing theouter bag 2 and the inner bag 3 is not limited to the above-mentioned means, and can be appropriately selected depending on the embodiment. For example, as another aspect of sewing, a corner portion on the side surface of the inner bag 3 may be sewn and fixed between the seam between the side surface portion 23 and the side surface portion 23 of the outer bag 2. Further, a fixing means other than sewing can also be adopted. For example, by attaching a convex part of the snap button to one of the outer bag 2 and the inner bag 3 and attaching a concave part to the other, both may be fixed by the button. Further, both may be fixed by a hook-and-loop fastener. That is, the fixing means may be a snap button, a hook-and-loop fastener, or the like.
外袋2と内袋3との固定手段は、上述の手段に限られず、実施の形態に応じて適宜選択することができる。例えば、縫い付けの別の態様として、外袋2の側面部23と側面部23との縫い目との間に、内袋3の側面のコーナー部が縫い込まれて固定されていてもよい。また、縫い付け以外の固定手段を採用することもできる。例えば、外袋2及び内袋3の一方にスナップボタンの凸パーツを取り付け、他方に凹パーツを取り付けることで、ボタンにより両者が固定されてもよい。さらに、両者は、面ファスナーによって固定されてもよい。つまり、固定手段は、スナップボタンや面ファスナー等であってもよい。 <3-9>
